The nature of state formation in early medieval India has been a subject of intense historical debate. Scholars have proposed different models to explain how political authority was organised between c. 600 and 1000 CE. Three major interpretations dominate this discussion: the Feudal Model, the Segmentary Model, and the Integrative Model, each offering a distinct understanding of power, territory, and social relations.

1. Feudal Model The feudal model, most prominently associated with R.S. Sharma, explains early medieval polity through the concept of ‘Indian feudalism’. According to this view, extensive land grants to Brahmans and officials led to political decentralisation. Powerful intermediaries such as samantas emerged, creating a hierarchical system marked by a bipolar relationship between lords and peasants. This model also emphasises the decline of trade, the growth of self-sufficient rural economies, and the fragmentation of central authority. Influenced by Marxist historiography, this approach highlights economic relations as the basis of political structure.
2. Segmentary Model The segmentary model, developed by Burton Stein, particularly in the context of South India and the Chola state, challenges the idea of administrative centralisation. It argues that the king exercised mainly ritual sovereignty, while real power remained dispersed among autonomous segments such as nadus, local chiefs, and village assemblies. Authority functioned through a pyramidal repetition of similar units rather than strict territorial control.
3. Integrative Model The integrative model, proposed by B.D. Chattopadhyaya, critiques the notion of political fragmentation. It focuses on long-term processes through which states expanded by integrating local polities, social groups, and cultural traditions. Emphasising regional dynamics and cultural integration, this model presents early medieval state formation as an evolving and adaptive process rather than one of decline.
